that the fbi has told you that theymissedtamerlanleavingthe country and going to russia because maybe his name was misspelled, that was one of the reasons given. we just heard from secretary napolitano that he did indeed, and these are her words, ping when he left the united states, and then the investigation seemed to be cleared during his time away. where ills the discrepancy? what is the truth? because it goes to the question, is our system working or isn't it? >> clearly it's not working. i'm dumbfounded wither 4 answer. i was told dar -- with her answer. i was told two nights ago in march they got a letter from the russian intelligence services that the older brother was a radical islamist, watch out for him. they claimed to have interviewed him. they interviewed his family. they went to the school he was attending and interviewed people. they sent the file back to russia in october of 2011, asked for more information and they never heard from them again and they claimed the system did not pick him going to russia in january of 2012 because the name was mis misspelled. now i hear fro

federal charges that he and his olderbrothertamerlanplantedpressure cooker bombs near the finish line for the boston marathon. tamerlan later died after a shootout with police. in providence, rhode island, lawyers for tamerlan tsarnaev's wife catherine said she had been unaware of the bombing plot. >> the reports of involvement by her husband and brother-in-law came as an absolute shock to them all. as a mother, a sister, a daughter, a wife, katie deeply mourns the pain and loss to innocent victims, students, law enforcement officers, families and our community. in the aftermath of this tragedy she, her daughter and her family are trying to come to terms with this event. >> woodruff: meanwhile, both the "washington post" and the "new york times" have reported that the younger tsarnaev admitted his role in the attack. the "post" also reported he told investigators that u.s. involvement in the iraq and afghanistan wars were motivating factors. other accounts said there appeared to be no links to larger terrorist groups. in russia today, their mother said f.b.i. agents talked to her abou
